Add a DT schema for describing nau8325 audio amplifiers. The key features
are as follows:
  - Low SPK_VDD Quiescent Current
  - Gain Setting with 2-wire interface
  - Powerful Stereo Class-D Amplifier
  - Low Output Noise
  - Low Current Shutdown Mode
  - Click-and Pop Suppression

Once again, use standard unit suffix on the property name: 

nuvoton,vref-impedance-ohms:
  enum: [0, 2500, 25000, 125000]

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC (and consider --no-git-fallback argument). It might
happen, that command when run on an older kernel, gives you outdated
entries. Therefore please be sure you base your patches on recent Linux
kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline), work on fork of kernel
(don't, instead use mainline) or you ignore some maintainers (really
don't). Just use b4 and everything should be fine, although remember
about `b4 prep --auto-to-cc` if you added new patches to the patchset.

You keep skipping maintainers on almost all your patches. Why?

Best regards,
Krzysztof

I'm so sorry. I will use scripts/get_maintainers.pl. to get a list of
necessary people for
check every send e-mail.

I'm so Sorry, I made a mistake. So, I will modify it as follows,
nuvoton,vref-impedance-ohms:
    description:
      The vref impedance to be used in ohms. Middle of voltage enables
      Tie-Off selection options. Due to the high impedance of the VREF
      pin, it is important to use a low-leakage capacitor.

    enum: [ 0, 25000, 125000, 2500 ]
